INTRODUCTION - Photovaporization of the prostate by the Greenlight(®) laser (GL) has been strongly developed this past few years in France, representing nearly 30% of surgery for BPH, making France the second GL user worldwide after USA.

Our objective was to describe the progressive introduction of photoselective vaporization of the prostate (PVP) in an academic department of urology in an outpatient care setting and report our outcomes after the first 100 cases.

Rare and severe complications of benign prostatic hyperplasia (BPH) surgery are poorly documented in the literature. Our purpose was to make an inventory of severe and unexpected complications of BPH faced by urologists of the French Association of Urology (AFU).

Surgical management of benign prostatic hyperplasia has dramatically changed in the recent years towards higher proportion of endoscopic treatment and fewer perioperative complications. Nevertheless the question of urinary and sexual quality of life after surgical treatment remains partially unresolved with a high proportion of retrograde ejaculation after conventional surgical treatments.

Despite its feasibility has been proven, Benign Prostatic Hyperplasia (BPH) day-case surgery remains uncommon. Our objective was to describe the evolution of BPH day-case surgery in France according to the surgical technique employed.

Benign prostatic hyperplasia (BPH) is the predominant cause of bladder outflow obstruction and is associated with significant morbidity. Surgical removal of adenoma has been a key treatment principle for alleviation of obstruction.

Current treatment strategies for stress urinary incontinence (SUI) raise concerns about safety and efficacy. The purpose of this systematic review was to present available evidence related to vaginal laser therapy as a treatment option for SUI.

To determine the influence of preoperative detrusor underactivity (DU) on serial long-term outcomes of HPS/PVP or HoLEP for LUTS/BPH, and to compare the influence between the two surgeries.

A total of 382 men, who underwent 120W-HPS/PVP or HoLEP for LUTS/BPH and for whom 36-month follow-up data were available, were classified into four groups: HPS with DU (n = 145), HPS without DU (n = 44), HoLEP with DU (n = 105), and HoLEP without DU (n = 88).

There are several options for the surgical management of benign prostatic hyperplasia representatively from transurethral resection of the prostate. Holmium laser enucleation of the prostate is one of those options, and many institutions and urologists have initiated this technique, and most of them have accomplished better outcomes compared with transurethral resection of the prostate.

There is scant evidence in the literature to support dusting stones vs active basket extraction during ureteroscopy for kidney stones. We sought to prospectively evaluate and follow patients to determine which modality produced a higher stone free rate with the least complications.

To investigate the impact of preoperative DU on serial treatment outcomes during five years after photovaporization (PV) or holmium laser enucleation (HoLEP) in BPH patients, to compare its impact between PV and HoLEP, and to identify predictors of long-term lower urinary tract symptoms (LUTS) improvement.

A select group of patients with upper tract urothelial carcinoma (UTUC) may meet indications for endoscopic management. Strategies for disease management are provided, based on a comprehensive review of the data using PubMed and Medline databases and marrying this with our experience with endoscopic management of UTUC.

With rising incidence of urolithiasis, treatment of stones (both symptomatic and asymptomatic) in multiple locations including bilateral stones can be controversial and challenging. We report our experience and treatment outcomes in patients undergoing bilateral, same-session ureterorenoscopy (BS-URS) for bilateral ureteric and/or renal calculi, and discuss the advantages and disadvantages of such procedures.

Vascular targeted photodynamic therapy (VTP) with WST11 (TOOKAD(®) Soluble; STEBA Biotech, Luxembourg) is a form of tissue ablation that may be used therapeutically for localized prostate cancer (PCa).

Focal therapy (FT) may offer a promising treatment option in the field of low to intermediate risk localized prostate cancer. The aim of this concept is to combine minimal morbidity with cancer control as well as maintain the possibility of retreatment.

There are currently 3holmium laser, YAG (Ho:YAG) endolithotripsy procedures that are considered basic (fragmentation, pulverisation, "pop-corn" technique). We present the technique of fragmentation targeted at preferred discontinuities (FTPD), a new concept of endolithotripsy by Ho:YAG laser.

Holmium:YAG laser is the most used laser for urolithiasis. Generally, we use metallic scissors to cut the fiber tip to restore its effectiveness. Many cleaving methods have been described to avoid fiber damage and to restore its greatest power to the fiber.

To evaluate the clinical safety profile for the use of gold nanoshells in patients with human prostate cancer. This follows on the nonclinical safety assessment of the AuroShell particles reported previously.

Gynecologist and plastic surgeons pioneered the application of lasers in medicine and surgery almost 5 decades ago, initially used to treat cervical and vaginal pathologies. Ever since, energy-based devices have been deployed to treat pelvic pathologies and improve fertility.

Prostate focal therapy offers men the opportunity to achieve oncological control while preserving sexual and urinary function. The prerequisites for successful focal therapy are to accurately identify, localize and completely ablate the clinically significant cancer(s) within the prostate.

Objective To describe our technique utilising photoselective vaporisation of the bladder (PVB) for the management of haemorrhagic cystitis and initial results of 12 patients. Materials and Method An audit of theatre records of a single surgeon was performed to identify patients who had undergone PVB for management of radiation-cystitis.

PURPOSE - Holmium:yttrium-aluminum-garnet (Ho:YAG) laser and Pneumatic cystolithotripsy (CL) are the most widely practiced transurethral procedures for treatment of pediatric bladder stones. The aim of our study was to compare the safety and efficacy of Ho:YAG laser CL and pneumatic CL in the treatment of pediatric bladder stones.

In this study, we aimed to evaluate the impact of preoperative anemia (PA) on oncological outcomes among patients with non-muscle-invasive bladder cancer (NMIBC) treated with GreenLight laser vaporization of bladder tumor (PV-BT).

Despite being endorsed in most of the guidelines, yet wide adoption of Holmium laser enucleation of the prostate (HoLEP) is hindered by learning difficulties. Herein, we prospectively assess its learning curve using multidimensional approach.

Ureteroscopy and laser fragmentation of stones is a commonly used method to treat ureteric and renal calculi. We report the exceedingly rare finding of a renal pseudoaneurysm in an interpolar renal artery following ureteroscopy and laser stone fragmentation, which was successfully managed with angioembolisation.

To investigate the prospective outcomes of day-case ureterorenoscopy (DC-URS) for stone disease. With the rising prevalence of stone disease in the face of finite resources, there is increasing pressure to undertake procedures as a day case avoiding in-patient stay.

Addressing vaginal laxity, atrophic vaginitis, stress urinary incontinence (SUI), and different manifestations of sexual dysfunction has always been problematic due to women's traditional difficulty discussing these issues with doctors as well as the societal attitude of resignation toward these conditions.

To look at the bibliometric publication trends on 'Urolithiasis' and aspects of treatment and training associated with it over a period of 16 years from 2000 to 2015. To this end, we conducted this study to look at the publication trends associated with urolithiasis, including the use of simulation, laser technology, and all types of interventions for it.

The prevalence of urolithiasis is increasing worldwide and is causing significant morbidity and cost to the healthcare systems. While ureteroscopy (URS) has been established as a treatment option, our review highlights the expanding role of URS for the management of more complex stones and patients in the modern era.
